Description of problem:
Install RHEL5 update 1 using kickstart. Specify a volume group name like
'mkearey-vg'. After package dep resolution and filesystem is successfully
created, the installer fails with a traceback stating :

OSError: [Errno2] No such file or directory: '/dev/mapper/mkearey-vg-rootvol'

Looking at the state of the system at the time of the failure, there exists
/dev/mapper/mkearey--vg-rootvol

Version-Release number of selected component (if applicable):


How reproducible:

100%


Steps to Reproduce:
1. Create a kickstart with the following partition details:

partition /boot --fstype=ext3 --size=200
partition pv.00 --size=1000 --grow

volgroup mkearey-vg pv.00

logvol / --fstype ext3 --vgname=mkearey-vg --name=rootvol --size=1000 --grow
logvol swap --fstype swap --name=swapvol --vgname=mkearey-vg --size=1000 --grow
--maxsize=2000

2. Begin the install, using ks=PATH_TO_KICKSTART_FILE 

  
Actual results:

anaconda python traceback including:
OSError: [Errno2] No such file or directory: '/dev/mapper/mkearey-vg-rootvol'

Expected results:
Clean install where dashes are allowed in both volume group and logical volume
names, and handled properly by anaconda
 
Additional info:

This problem is likely to affect all releases of RHEL5 not just update 1.
